Self-adaptive adjustment method based on ambient light distribution field

Abstract

A self-adaptive adjustment method based on an ambient light distribution field comprises: obtaining a background image of a background environment in a viewing angle range of a user (101); obtaining pixel information of a single pixel point / multi-pixel-point block in the background image (102); calculating / extracting illumination information of the single pixel point / the multi-pixel-point block from the pixel information (103); obtaining continuous background image illumination field information according to the illumination information (104); performing matching calculation on the background image brightness field information and preset illumination field distribution models to obtain a corresponding first illumination field distribution model (105); querying a model-parameter list to obtain a first adjustment parameter corresponding to a first illumination field distribution model (106); and adjusting a display parameter of a display screen of a user terminal and / or adjusting a light supplementation output parameters of a lighting compensation device, so that the display parameters of the display screen match the illumination state of the background environment in the viewing angle range of the user (107).

AI Technical Summary

Benefits of technology

This method effectively adjusts display settings to match the ambient light distribution, reducing eye strain and improving visual health by accurately reflecting the background environment's illumination, even when light intensity is non-uniform.

Problems solved by technology

Besides, with the advancement of digital working and teaching, office workers and students spend a lot of time staring at computer screens and projection screens every day.

After frequent and long-time looking at the display screens of mobile phones, computers and other terminals, eye strain can be caused, which further leads to decreased vision and affects visual health.

However, the display screens of these electronic devices rarely have adaptive illumination.

For example, most televisions and computers do not have adaptive illumination.

1. At present, most smart phones with the automatic illumination adjustment mode detect the illumination of the background environment identifying the ambient light with a illumination sensor, and then calculate the screen display illumination according to a preset algorithm; the illumination sensors of mobile phones are typically disposed on the front of mobile phones, that is, facing the users, while the visual background of the users faces the back of mobile phones; as a result, the illumination sensor cannot really perceive the background environment from the users' perspective, which is one limitation of the current automatic illumination adjustment method of display screens;

2. The illumination sensor of the mobile phone is a point, which can only sense the illumination irradiated by this point, but the user's background is a plane, so the sensor cannot reflect the whole use background faced by the user;

3. The illumination adjustment of mobile phones is based on the light of the illumination sensor, so it is assumed the light is evenly distributed, but the reality is that the users' background light intensity cannot be uniform all the time, and the use background has illumination field distribution.
